I have a problem : i've two domain : domain1.tld and domain2.tld.
All my users are created in domain1.tld and i would like that my users could use firstname.lastname@example.org or email@example.com for log and for check their emails.
Do you think it's possible?
I use Postfix with Dovecot and MySQL.
Sorry for my english it's not my mother tongue.
Thanks in advance
